Sex Drugs and Texting 287

statesman writes "The Associated Press reports that teens who text frequently are three and a half times more likely to have sex. A survey of 4,200 public high school students in the Cleveland area found that one in five students sent more than 120 text messages a day or spent more than 3 hours a day on Facebook. Students in this group were much more likely to have sex. Alcohol and drug use also correlate with frequent texting and heavy Facebook use."

Religious Ceremony Leads To Evolution of Cave Fish 233

An anonymous reader writes "A centuries-old religious ceremony of an indigenous people in southern Mexico has led to evolutionary changes in a local species of fish, say researchers at Texas A&M University. Apparently since before Columbus arrived, the Zoque people would venture each spring into the sulfuric cave Cueva del Azufre to beg the gods for bountiful rain. As part of the ritual, they released into the cave's waters a leaf-bound paste made of lime and the ground-up root of the barbasco plant, a natural fish toxin. The rest is worth reading, but the upshot is that the fish living in the cave waters eventually got wise, genetically speaking."

Portal 2 Gets Release Date 110

AndrewGOO9 writes "After what has seemed like an eternity since Valve initially announced a sequel to their lauded puzzle title Portal, a release date has finally been attached to the game. Originally slated to be released before the end of the year in time for the holidays, Valve instead opted to delay the game, citing reasons such as, 'making games is hard' as well as continuing their tradition of releasing games when they're finished as opposed to rushing them out the door. Either way, mark your calendars for February 9th, 2011, and in the meantime, brush up on thinking with portals." There's some new gameplay footage available, and Valve announced that Stephen Merchant will be lending his voice to the game.

Well, yes, but the fourth core was still locked, and in many cases was fully functional. They just locked a core on a quad core to avoid the cost of retooling to produce the triple core design when market demand exceeded the number of failed chips.

I may be missing a split hair someplace, but in case you haven't played with them AMD sold a bunch of defective quad cores as triple cores with the defective one locked. A lot of the time they still worked fine.

Hmmm, well, I can't say I agree with that- I've open sourced the work I've done on Apple's OSX updater, various crypto toolkits, etc, and have never seen anybody do anything about it until I've either contacted them directly or released it into the wild- but, it's your code so you're the boss.

Anyways, if you'd like to collaborate drop me an email- my username@gmail.com.

when you change just one character on the input if you use a good algorithm (sha2 or rijndael aka AES) so it's difficult, if not impossible to predict what change will happen in the hash by changing the input, if you don't know the secret and initialization vector.

AES is not a hash. AES is a symmetric block cipher.
